I think there should be some party/team(these are concept words not actuals)battles, with rewards , lets say you team battle and you rank up honor/valor(could be any name just examples) and then you trade this in for things like potions,weapons,armors,ect that are only team/party battle items.

This would be cool because it rewards you for being a team player, you would be awarded these things for kills,assist,combo kills(killing alot of people without dying)for healing team mates,ect just some examples.

I think for a game basically based on the concept of pvp this would be awesome, While it will have quest and npc's to kill it would be awesome to have this style of gameplay as well.

I could go more into this idea but im leaving this open for the community to come in and also contribute on the idea, it takes more than one person to make something good
